“petition is warranted given the number of claims at issue. See Trial Practice Guide 59 (identifying situations where “two petitions . . . may be needed”). Patent Owner has asserted 166 claims in the co-pending district court litigation, and Petitioner challenges 91 unique claims in these petitions. See Ranking Notice 2; Ranking Response 2. Also, the vast majority of the challenged claims are asserted in litigation. See Ranking Response 2; Ex. 2004, 3. As a result, we agree that this is the type of “rare” situation where multiple parallel petitions are necessary. Petitioner’s primary argument is that seven petitions were required because the common sections needed to be repeated in each petition, which left few words for arguments directed to new claims (given word count limits). See Ranking Notice 2–3. But this argument is premised on an assumption that these common sections “require[d] approximately 8,350 words” (id. at 3), and Petitioner has not persuasively shown that so many words were actually required for these sections. Petitioner includes no explanation or justification of the length of the sections, but instead, it simply assumes that the words used were required. Having reviewed the analysis in those sections, we do not agree. In other words, although we agree that the common sections needed to be repeated in each petition (and that this reduced the number of words available for other analysis), we are not persuaded that the common sections required approximately 8,350 words. A petitioner is certainly entitled to allocate its words as it sees fit, and we typically have no reason to evaluate those strategic decisions; however, we agree with Patent Owner (see Ranking Response 3) that Petitioner cannot justify a large number of petitions by claiming that it needed additional words for its analysis (given the Board’s word count limits) unless Petitioner’s analysis was concise. 10 A petitioner is not entitled to an unlimited number of petitions (see Trial Practice Guide 59–61); instead, we determine whether the circumstances justify additional petitions (see id. at 59–60). This approach conforms with the rationale behind imposing a word count limit on petitions. See id. at 39 (discussing the reasons for establishing word count limits and urging parties to present “concise, well-organized, easy-to-follow arguments supported by readily identifiable evidence of record.”). i.e., the analysis of claim 2, the summary of the ’754 patent and prior art, the articulation of the level of skill in the art and claim construction, and the other preliminary comments—and we are not persuaded that they are sufficiently concise to support Petitioner’s argument. Claim 2 is only fifteen lines long, and its technology is relatively simple, yet Petitioner’s analysis of this claim stretches for seventeen pages. See Pet. 24–41. Petitioner provides no general information about the technology and submits that no claims need to be construed (id. at 7), yet Petitioner provides a five-page summary of the ’754 patent and its prosecution history (see id. at 2–6). Also, Petitioner provides a twelve-page summary of Ahn and Chaudhri (see id. at 7–19), despite the fact that neither reference is particularly long. Indeed, as Patent Owner notes, Petitioner was able to remove nearly 1,000 words from these common sections in at least one of the petitions. See Ranking Response 3–4. Because Petitioner’s analysis in the common sections does not appear to be concise, we are not persuaded that Petitioner’s use of approximately 8,350 words in those sections justifies the large number of petitions.” slip op. at 11

Petitioner, however, contends that “this claim term is not part of the preamble” and that “the preamble is [only] ‘In a multi-user detection system in which interfering signals are purposely allowed to exist.’” Pet. 14. Regardless, Petitioner further contends, to the extent there is any argument that that recitation is part of the preamble, “it is limiting at least because it provides antecedent basis to the ‘parameter estimation unit’ and ‘associated channel transfer functions’ terms that are used in the remainder of the body of the claims and is ‘essential to understanding the structural limitations’ of the parameter estimation unit.” Id. Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp. As reproduced in Section II.D. above, the preamble of claim 1, in its entirety, recites, “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit, in which each received signal has associated channel transfer functions.” Ex. 1001, 12:41–45. The preamble of claim 9 is similar. Id. at 14:3–7 (reciting “In a multi-user detection system in which interfering signals are purposely allowed to exist, a parameter estimation unit for use in conjunction with a signal separation unit for estimating channel transfer function parameters from channel transfer functions”). The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Because the ’676 patent has a filing date before September 16, 2012 (effective date of the statute), we refer to the pre-AIA version of 35 U.S.C. § 112. associates that structure to the function recited in the claim.” Med. Instrumentation & Diagnostics Corp. v. Elekta AB, 344 F.3d 1205, 1210 (Fed. Cir. 2003). Our Rules specifically require that the petition identify the corresponding structure in proposing a construction for a means-plus-function claim limitation. 37 C.F.R. § 42.104(b)(3). “This inquiry is undertaken from the perspective of a person of ordinary skill in the art.” Cardiac Pacemakers, 296 F.3d at 1113.” slip op. at 19

Institution was denied: claims 1–16 lacked a reasonable likelihood of success, and the Board declined to reach claims 17–18 because reviewing only two potentially viable claims would be inefficient.

“as of the time of the invention of the ’492 Patent “had at least a bachelor’s in EE/CE/CS, physics, or equivalent, and two years of experience with cellular telecommunications, radio-access network architectures, protocols and signal propagation in wireless networks. More education can supplement practical experience and vice versa.” Pet. 5 (citation omitted). Patent Owner does not dispute Petitioner’s assertion. At this juncture, we adopt Petitioner’s definition. This definition appears to be consistent with what is reflected by the content of the applied prior art references. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (recognizing that the applied prior art may reflect an appropriate level of skill).” slip op. at 9

“In view of the parties’ agreement to adopt Patent Owner’s construction and the District Court’s persuasive analysis, we find that the “multi-user detector decision unit” terms in claims 1 and 10 are properly construed on the record before us to recite the functions “using decision criteria to determine a selected multi-user detector” for claim 1 and “select[ing] a multi-user detector based upon at least one threshold” for claim 10, both of which have the following corresponding structure: a MUD decision unit 220 (or, alternatively, decision logic unit 520) configured to perform one or more of the several decision algorithms (e.g., the BER/User, SINR/Symbol, Filtered SINR/Symbol, Detected Amount/Symbol, Correlation Matrix Ratio/User, Correlation Matrix Eigenvalues, Computational Complexity, Number of Bits, Number of Users, and other algorithms) disclosed at 8:12–18, 13:35–14:40, 15:3–21, 19:43– 48, 19:56–62, and 20:41–49 of the ’492 Patent.” slip op. at 12

“a reasonable likelihood of success in establishing that Onggosanusi teaches or suggests these limitations. Petitioner does not rely on Egnor for these limitations. Therefore, Petitioner fails to show a reasonable likelihood of success in establishing that claims 1 and 10 would have been obvious over Onggosanusi and Egnor. Claims 2–9 and 11–16 depend from claims 1 and 10 respectively, and thus Petitioner likewise fails to show a reasonable likelihood of success that those dependent claims would have been obvious over Onggosanusi and Egnor. Therefore, we find that Petitioner fails to show a reasonable likelihood of success for Ground 1.” slip op. at 15

“Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”). “Even when a petitioner demonstrates a reasonable likelihood of prevailing with respect to one or more claims, . . . institution of review remains discretionary.” Chevron Oronite Co. v. Infineum USA L.P., IPR2018-00923, Paper 9 at 10 (PTAB Nov. 7, 2018) (informative) (citing SAS Inst. v. Iancu, 138 S. Ct. 1348, 1356 (2018); Harmonic, 815 F.3d at 1367). Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources. See, e.g., Deeper, UAB v. Vexilar, Inc., IPR2018-01310, Paper 7 at 42–43 (PTAB Jan. 24, 2019) (informative) (denying institution where a petitioner demonstrated a reasonable likelihood of success on only two out of twenty- a petitioner demonstrated a reasonable likelihood of success on only two out of twenty claims). Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims. Accordingly, we need not, and do not, take any position as to Petitioner’s showing on Ground 2 but instead exercise our discretion to deny review.” slip op. at 21
